CHARLES TAYLOR, ()F MONTREAL, QUEBEC, CANADA, ASSIGNOR OF ONE- HALF OF HIS RIGHT TO GEORGE HlRAM KENDALL, OF SAME PLACE.

MOWING AND REAPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 225,663, dated March 16, 1880.

Application filed December 31. 1879.

To all whom it may concern Be it known that I, CHARLES TAYLOR, of the city ofMontreal, in the District of Montreal, and Province ofQuebec, Canada, haveinvented certain new and useful Improvements in Mowing and Reaping Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention has reference to the mechanism which imparts to the knife its reciprocating motion and the device which I have invented for the above purpose may be described as a compound lever pivoted at its rear end to the frame, actuating the pitman, and operated by corrugated wheels mounted on the main axle.

It may be thus briefly described: Upon the rotating main axle of the machine I secure two wheels, having the inner edges of their peripheries formed by a series of obtuse angles, the wheels being so set that the apices of the salient angles are opposite to each other, and between these wheels I place two short arcs or plates corresponding to the curve of the wheel, connected together by a link pivoted to the rear arc, and either made in one with or forming" a continuation of an arm rigidly attached to the front are, and connected with the pitman operating the knife, all these parts thus forming a compound lever between the projection of the frame, to which a link, pivoted to the rear arc, is pivoted, and the end of the pitman. These arcs or plates have their edges formed of a series of obtuse angles corresponding to those on the wheels, but with parallel sides and internal and salient angles opposite to each other.

For fuller comprehension, however, of the invention, reference must be had to the annexed drawings, in which- Figure l is a plan View of a machine embodying my invention. Fig. 2 is a sectional elevation on line :10 w, Fig.1, showing operating mechanism.

Similar letters of reference indicate like parts.

Ais themain axle of themachine, upon which the frame Z is hung in any usual way, and receiving motion from one of the driving-wheels B B, keyed thereon, as maybe desired, and to be more particularly described farther on. Upon this shaft A are mounted rigidly two disks 01' wheels, 0 and D, the inner peripheries of which are, as shown at c and (I, formed ofa series of obtuse angles opposite to each 5 other-4. 0., salient angles to salient angles and internal angles to internal angles-C and D being rings set respectively inside the peripheries of C and D,and serving to carry the arcs E and F, the rear one, E, of which is pivoted by a link, E, to a projection, Z, formed on the frame, and also secured to the are F by a link, G, pivoted to E.

H is a bridge or steadiment, which may be, if desired, placed below the rings 0 D and the link G connected thereto to keep the arcs E Fin place. The link G either passes through the arc F and is connected at its other end to the pitman I, as shown in Fig. 2, or it may be simply rigidly attached to F, and the part secured to and projecting from F, to operate the pitman, be a separate arm. The edges 0 e ff of these arcs E and F are formed of obtuse angles corresponding to those 0 d of the wheels 0 D, as shown in Fig. 1, but in this case having the internal angles on one side corresponding to the projecting angles on the other. K is the fin ger-bar, and L the knife, all these, with other parts of the machine not specially referred to, being of any usual and suitable construction.

The operation of this part of my invention will be so clearly understood from the foregoing, and from the drawings, that it will only be necessary to say that in the revolution of the 8 5 disks C D their edges 0 and at act upon the edges 0 c f f of the arcs, and, moving them alternately laterally in either direction, impart through the lever or arm G j the necessary throw to the pitman, the point at which the link G is pivoted to the are E being the fulcrum-point of the compound lever.

It must, too, be observed that by the arrangement shown andldescribed, when theledges c of the are or plate E are in close contact with 5 the edge cl of the wheel D, the edgesfof the are F are in similar contact with the edges 0 of the wheel 0, and vice versa, thus giving perfectly positive action in either direction, and also great steadiness of working and freedom 10o from uncontrolled or loose play, and although as the operating-surfaces slide past each other there is no impact, any Wear may be compensated for by packing the junction of the hubs of the wheels 0 and I) and securing them adjustably together by means of set-screws.

The construction above described of the operatingmechanism maybe modified, as will now be described, without, however, changing the principal feature of the invention-via, the compound lever.

Instead of the two wheels 0 D, but one may be used, having on its periphery a ridge formed of a series of obtuse angles, and having its sides parallel in the same outline as the ares E and F, upon which rest the vibrating ares or plates, in this case recessed so as to form surfaces of a series of obtuse angles with their salient points opposite to each other, the same as the edges 0 d, the ridge operatin g the blocks in the same manner as before described by simultaneously bearing against opposite surfaces.

I am aware that pivoted levers actuated by corrugated or wave surfaces and connected with the pitman have been employed in mowing-machines to give the necessary vibratory motion to the knife; butin all these instances the lever used was a simple one and the apices of these waves or corrugations alternated.

What I claim is as follows 1. Ina mowing or reaping machine, the combination of the following elements, viz: the compound lever formed of the are E, pivoted by a link to the frame, the link G, pivoted to said are and attached to are F, carrying arm connected with pitman, said arcs having their sides parallel and edges of obtuse angles, and being moved laterally in either direction by the rotation of two wheels mounted on main axle, and having their edges composed of corresponding obtuse angles set with their salient points opposite to each other, all substantially as herein set forth.

2. The combination of parallel-sided obtuseangled surfaces with similar obtuse-angled surfaces having their salient points opposite to each other, either of these operating or receiving motion from the others, and the surfaces receiaving motion being pivoted together, all as herein set forth, and for the purposes described.

CHARLES TAYLOR.
